Neher has its finger on the VPulse

Ostrach-based family business Neher, which develops special tools for the international manufacturing industry, recently opted to invest in a VPulse 500 wire-erosion machine from Vollmer. Developed by the Biberach-based sharpening specialist, the Vollmer machine allows Neher to manufacture its PCD-tipped tools with a high surface finish.

“We manufacture customised diamond tools for our customers, which generally have complex geometries, particularly when it comes to combination tools such as milling cutters and reamers”, states Gerd Neher, managing director of the Neher Group. “For this we rely on erosion technology from Vollmer and recently decided to purchase the fully automated VPulse 500.”
Neher uses wire erosion for processing its PCD cutting edges. The process is suitable for tools such as contour cutters or stepped reamers that have complex geometries. With the Vollmer VPulse 500 wire-erosion machine, even the tiniest inner radii can be machined precisely. Typically, special tools require machining times that range from 30 minutes for simple reamers up to 20 hours for complex combination tools.
“Thanks to the fully automated VPulse 500 we can work in single-shift operation and still manufacture around the clock, and over the weekend”, states Anton Juric, application engineer at Neher. “For this, we use the external tool memory of the wire-erosion machine where we can store a total of 16 different tools.”
Neher is currently planning on purchasing another VPulse 500 to boost its targeted level of growth. In 2017, Neher concluded a joint venture with the American company Star SU from Michigan. With locations in the USA, Canada, Mexico and Brazil, the plan is to now use the new VPulse 500 on site in the USA.
